Miscellaneous Notes on XE

• Need to stay current with Banner 8 • It is modular but beware of dependencies• You can implement only the apps you want (can also

continue to use Banner 8 and ease into it)• Been slower to adopt then we initially thought. • Really version 1.0, 1.1, … (not 9.0, 9.1, …) of a new

application (should get better over time)

Banner XE Architecture

• Why WebLogic?

o Oracle Site License

o 24X7 Oracle Support

o WebLogic Familiarity (Existing Forms/Self-Service Environment)

Banner XE Architecture• Environment Setup

Banner XE Architecture• Web Tier Setup

o OHS1 used for all non-administrative applications. No firewall restrictions.

o OHS2 used for all administrative applications. Firewalled to campus users.

o Multiple Development/Test environments running simultaneously.

o Banner instances differentiated with -SIDNAME

o Web Tier mod_wl_ohs.conf used to route application to specific WebLogic managed servers.

Banner XE Architecture• Managing Banner databases

o Modification configuration files to maintain –SIDNAME

Banner XE Architecture• Issues managing multiple Banner databases

o Configuration file management.• Creation of scripts to centrally manage and maintain mod_wl_ohs.conf and Banner

instances between application servers.

o “Banner Already Open in Another Window” error.• Manual extraction and editing if WEB-INF/weblogic.xml cookie-path.

Banner XE Modifications

Banner XE Modifications• Illinois has many local modifications to Ellucian

products such as Oracle Forms and Self-Service applications. This need is still required with XE technology.

• Requirements• Access to source code for Application Support and Developers.• Processes to restrict access to source code.• Tools to modify and test changes.• Processes to document and distribute changes for technical users.

Banner XE ModificationsGit Repository Setup

o Illinois git origin server• Red Hat Enterprise Linux Server release 6.7• ssh key exchanged with Ellucian to access source git repositories• Create local master branch for modification• Git repositories are secured with gitolite

- ssh keys exchanged with technical team and developers to access repositories- Allows setting read/write access to git repositories via gitolite.conf

repo banner_student_registration_appRW+ = user1R = user2- local-master = user3

• Modifications to source done via IntelliJ or git bash

Banner XE ModificationsGit Repository Process

o Create bare repository from Ellucian source.• Create single bare repository or use script to create all available repositories.

o Create local master branch for modification.• Find latest version and create local master branch

o Update .gitmodules to point to local origin server

o Update project submodules.

o Clean the application. **This can be time consuming

Banner XE ModificationsGit Repository Process (continued)

• Make modifications to the code

• Compile

• Run locally to test changes.

• Include readme file with specific changes for technical teams.

• Package up and deploy to WebLogic Server.

Banner XE ModificationsModifying XE with code changes

o Simple modification, increasing length of a field from 2 to 4

• Example; Student Schedule App

• Modified plugins/banner_general_common.git/src/groovy/net/hedtech/banner/general/overall/SectionCrossListSection.groovyincreasing length of cross list column to 4.

• @Column(name = "SSRXLST_XLST_GROUP", nullable = false, length = 2)

Changed to

• @Column(name = "SSRXLST_XLST_GROUP", nullable = false, length = 4)

o Advanced modification, disabling Last Attend Date and Hours Attended• Example; Student Faculty Grade Entry• Functional team needed a way to ignore Last Attend Date and Hours Attended when importing Midterm Grades• Before modification

o Advanced modification, disabling Last Attend Date and Hours Attended• Example; Student Faculty Grade Entry• Functional team needed a way to ignore Last Attend Date and Hours Attended when importing Midterm Grades• Modified

grails-app/controllers/net/hedtech/banner/student/utils/ImportController.groovy

Original Code Allowed Last Attend Date and Hours Attended to be mapped when importing Midterm Gradesdef columns = validCourseRosterColumnsif (session.selectedSection?.gradingType == "midterm") {

columns = columns.findAll {it.key != "finalgrade" && it.key != "incompletefinalgrade" && it.key != "extensiondate"

o Advanced modification, disabling Last Attend Date and Hours Attended• Example; Student Faculty Grade Entry• Functional team needed a way to ignore Last Attend Date and Hours Attended when importing Midterm Grades• After modification

o Advanced modification, disabling Last Attend Date and Hours Attended• Example; Student Faculty Grade Entry• Functional team needed a way to ignore Last Attend Date and Hours Attended when importing Midterm Grades• Modified

grails-app/controllers/net/hedtech/banner/student/utils/ImportController.groovy

Modified Code Ignored Last Attend Date and Hours Attended mappings when importing Midterm Grades by adding lastattenddate and hoursattended columns to logic. Change highlighted in red.

def columns = validCourseRosterColumnsif (session.selectedSection?.gradingType == "midterm")

columns = columns.findAll {it.key != "finalgrade" && it.key != "incompletefinalgrade" && it.key != "extensiondate" && it.key !=

"lastattendeddate" && it.key != "hoursattended"}

Banner XE ModificationsModifying XE without code changes

o Modifying XE through CSS and js• Include bannerSelfService-custom.css and bannerSelfService-custom.js in XE war.

• Allows for Institutional Branding, removing the Ellucian University logo in upper left of browser..institutionalBranding {

background: url("./images/logo.gif") no-repeat;}

• Allows hiding of columns/buttons without modifying source code. Example, Student Facult Grade Entry

#browseButton {visibility: hidden;

• Using browser developer tools makes finding elements easier.

Banner XE ModificationsGit/Grails Challenges

o Learning and integrating new modification process into existing procedures

o Maintaining changes to application plugins that are used by multiple XE applications

o Windows specific issues• Some groovy files needed to be changed to accommodate Windows paths. “grails not found”• Setting fileformat=unix when editing some files

o Local workstation resources when cleaning, compiling, and running apps locally. Need a good amount of RAM if workstation isn’t dedicated to modifications.

Tips/Troubleshooting XE

Skills needed to support XE

• Existing expert knowledge of Banner 8• Java => Groovy and Grails• Web 2.0 (HTML5, CSS, JavaScript, AJAX, jQuery, JSON)• Java Middle Tier (tomcat or WebLogic)• Oracle database• Git (source control)• IDE (IntelliJ or Eclipse)• Persistence and time…

Resources

• eCommunities/BORACLE• Get involved in early adopter/beta efforts (good for

contacts)• Literature (Grails in Action/Groovy in Action)• Ellucian training on XE development• Lot of free resources in terms of Git, HTML5, Javascript,

JQuery and Java• Groovy and Grails is a little spotty on google

Browsers

• Works well with Chrome and Firefox (haven’t tested much with Safari)

• Don’t recommend IE. IE8 JavaScript was REALLY slow. Faster now but have seen issues with things not displaying properly

• Keeping in mind that Chrome and Edge (cannot run Banner 8 Forms). Firefox targeting end of the year.

Browsers for troubleshooting

• Chrome Developer Tools are your friend!! (View-> Developer -> Developer Tools)

• Assists with performance, response headers, CSS manipulation, cookies, errors, etc..

• For Firefox there is (Tools -> Web Developer)• Other tools include Firebug, Fiddler, SAML tracer

(setting up SAML), etc…• Something for every browser

Chrome Dev Tools

1.) Click on Search Terms Drop Down

2.) Review Background AJAX calls 3.) Evaluate Performance

Chrome Dev Tools cont…

1.) Highlight “getTerms” request

2.) Click on “Preview” tab then view payload from “getTerms” request

Finding source code from urlURL: https//host/StudentRegistrationSSB/ssb/classRegistration/getTerms

Chrome Dev Tools CSS fun!!

1.) Goal – modify the appearance

2.) Click “Elements” tab and highlight “select2-results” class for example

3.) Elements on page automatically highlight and css shows up on right

Chrome Dev Tools CSS fun cont..

1.) Click Add

2.) Add some css

3.) Changes magically appear!!

Add css changes to XE app

• Create or modify $BANNER_HOME/xe_app/instance/config/css/bannerSelfService-custom.css file

• ul#select2-results {color: red;

}• Save the changes and rebuild and deploy• We’ve done this to effectively hide fields, columns, etc..

Application Log File

• Comes with every application and can be customized in terms filename/directory/logging level

• First place to start with issues• Inside file StudentRegistrationSsb_configuration.groovy

log4j = {def String loggingFileDir = "/u01/app/oracle/Apache_logs"def String logAppName = "StudentRegistrationSSB-BANDR1"def String loggingFileName = "${loggingFileDir}/${logAppName}.log".toString()appenders {

rollingFile name:'appLog', file:loggingFileName, maxFileSize:"${10*1024*1024}", maxBackupIndex:10, layout:pattern( conversionPattern: '%d{[EEE, dd-MMM-yyyy @ HH:mm:ss.SSS]} [%t] %-5p %c %x - %m%n' )

custom logging directorycustom log file name

Application Log Error

specific error place in code where error occurred

XE Application debugging

• XE comes with log4j built into it• Can modify logging level across board (careful with

VERY large log files with trace or debug)• Can enable logging for individual packages or classes• Can customize log file name and directory• Changes made to [appname]_configuration.groovy then

rebuild and deploy• JMX extensions for dynamic logging (haven’t tried yet)• Customized logging by modifying code/rebuild/redeploy

Global Log Change

• Global log change using root logger in [appname]_configuration.groovy

• Log levels (off, fatal, error, warn, info, debug, trace, all)

case 'production':root {

error 'appLog'additivity = true

log level

Output to defined appender or default “stdout”

Targeted log change

e.g. having authentication issues??// ******* Security framework classes **********

trace 'net.hedtech.banner.security'trace 'net.hedtech.banner.db'trace 'net.hedtech.banner.security.BannerAccessDecisionVoter'trace 'net.hedtech.banner.security.BannerAuthenticationProvider'off 'net.hedtech.banner.security.CasAuthenticationProvider'trace 'net.hedtech.banner.security.SelfServiceBannerAuthenticationProvider'trace 'grails.plugins.springsecurity'trace 'org.springframework.security'trace 'org.apache.http.headers‘trace 'org.apache.http.wire'

Custom log changeUsing getTerms again as example, add following sample code to ClassRegistrationController.groovy then run locally

add debug code

Custom logging output

• View output in log or stdout• Output of “terms” is nicely displayed automatically

Oracle AWR reporting

• AWR (Automated Workload Repository)• Note – does require diagnostics pack license• Database snapshots taken every hour by default (or

manually)• The awrrpt.sql SQL script generates an HTML or text report

that displays statistics for a range of snapshot Ids.• I like to isolate in a dev/test environment and run

something• Essential for use in load testing• Great for “generically” tracing a connection pool

AWR in action/Reg XE Load testing

BEFORE

AFTER JDBC Caching

Disaster!!!

AWR features

AWR header

SQL ordered by elapsed time

SQL report options

2 queries 67% of activity!!

Summary

• It’s a luxury to be able to use Banner 8 while you get ramped up on XE (now’s the time!!)

• Ease your way into it/get comfortable with the technologies and architecture – there is a learning curve

• Make some mods if only for the practice of seeing it all put together
